Research Project: NUTRITIONAL MODULATION OF GAIT AND COGNITION IN AGING

Location: Human Nutrition Research Center on Aging

Project Number: 1950-51000-070-10
Project Type: Specific Cooperative Agreement

Start Date: Jun 01, 2009
End Date: May 31, 2014

Objective:
Establish the effects of nutritional modulation (e.g., berry fruit) on behavioral (e.g., cognition, gait, force and balance) and neuronal deficits in aging to assess the mechanisms involved and the most effective dietary supplements in animal and human models.

Approach:
Conduct studies using a specialized Noraxon treadmill in order to measure parameters of gait including balance, stepping up and down, and walking patterns in humans. These new studies will allow us to focus on more subtle variations in gait that include stride to stride fluctuations (e.g., symmetry) and associated alterations in electromyography (EMG). The Noraxon measurement system allows an objective kinematic analysis of the human gait by means of analyzing the tracks of body surface markers. Additionally, cognition will be measured with a battery of tests that measure memory and vigilance.
